Answer
The path of a charged particle in a cyclotron is circular or spiral. This shape is due to the perpendicular magnetic field that influences the charged particle's motion, causing it to move in a circular trajectory while it accelerates.
Step 2
Explain how radioactive isotopes can be produced using cyclotrons.

Answer
Radioactive isotopes can be produced in cyclotrons by bombarding stable nuclei with fast-moving protons. When these protons collide with the nuclei, they can be absorbed, leading to the creation of unstable nuclei that subsequently decay into radioactive isotopes.

Answer
Momentum is defined as the product of mass and velocity. Therefore, since mass is measured in kilograms (kg) and velocity in meters per second (m/s), the resulting unit of momentum is kg.m/s.
